PNEUMATIC PUMP.

Specification of Letters Patent.

Patented July ill, 1916.

Application filed April 29, 1915. Serial No. 24,691.

Tn all whom it 'may concern:

Be it known that I, JOSEPH S. HATTERY, a citizen of the United States ofAmerica, and a resident of "Waterloo, Blackhawk county, lowa, haveinvented certain new and useful Improvements in Pneumatic Pumps, ofwhich the following is a specification.

My invention relates to improvements in pneumatically actuated pumps,wherein compressed air is employed to elevate the water column, and theobject of my improvement is to supply in such a. device means fordirecting the entering current of air or fiuid under pressure upwardlyand divergingly toward the inner wall of the water conduit so as to moreefficiently act in elevating the water supplied to said conduit. Thisobject l have accomplished by the means which are hereinafter describedand f' claimed, and which are illustrated in the a-b of Fig. 1. Fig. 3is a detail perspective view of the sprayer or deflecting device of mysaid invention.

Similar numerals of reference denote corresponding parts throughout theseveral views.

My improved device comprises a main casting 1 forming a substantiallytubular chamber 16, the latter passing vertically through the casting.The open upper and lower ends of said casting are interiorly threaded,the upper opening 7 to receive the lower end of an upwardly directedconduit or pipe 8 supplied adjacent to said casting with a plurality ofsmall orifices or inletopenings 9. The opening 10 at the lower end ofsaid casting is adapted to receive detachably a depending pipe l1 whichis pref erably reduced in diameter a short distance below the casting sothat the reduced part may be more easily seated in a drill hole or pitunderneath.

The numeral 3 denotes a tubular body located centrally within thechamber 16 with its bore 17 alined with said chamber longitudinally andconcentrically and equally spaced from the inner wall of the saidchamber, while its open ends are equally spaced away from the open endsof the chamber. The said body 3 is integrally supported within saidchamber on one side by means of a relatively narrow vertical web 18, and

on the other side integrally by the wall of a short tubular conduit 19opening outwardly through the wall of the chamber into an upwardlydirected pipe seat or connection 2. The upper part of the body 3 isslopingly coned or expanded upwardly from the point where it receivesthe conduit 19, while the lower part of the bore 4 of said body is narrower and cylindrical and provided with threaded parts 5 and 6 at itsupper and lower ends.

-The numeral 12 denotes an upwardly coned sprayer-head having a squaresocket 13 in its top for the introduction of a socketwrench. Said headhas an integral depending diminished cylindrical stem 14 terminating inan exteriorly threaded wider part 15, which latter is detachably seatedin the upper threaded part 5 of the bore 4 of the body3. The stem ofsaid head is spaced away from the sloping inner wall of the body 3 andis set opposite the horizontal part of the bore of the conduit 19. rlheconical part 12 extends from the hollow 17 ofthe body 3 upwardly andinto the open lower end of the vertical pipe or water conduit 8 a littleWay with its upper edge or angular part spaced equally from the innerwall of said conduit.

The parts described when located in a well in the usual way, and theconduit 19-2 placed by means of a pipe or other suitable connection incommunication with a supply of fluid under pressure or compressed air ata proper pressure is adapted to elevate water or other liquid receivedinto the upwardly directed conduit 8 through the orifices 9. Thecompressed air passing into the flaring hollow 17 of the inner tubularbody 3, passes upwardly over the inclined surface of the inverted cone12, which spreads the current and directs it upwardly and obliquely allaround against the inner wall of the conduit 8 and underneath theorifices 9. The air in ascending along the wall of said conduit, Sweepsstrongly thereover while simultaneously expanding inwardly and thus morecompletely and efficiently buoys up and drives before it the enteringstreams of water passing through said inlet. ln case any sand, mud, orother solid matter enters into the conduit 8 through the orifices 9 withthe water, such matter may drop between the head 12, the inner body 3,and the inner wall of said chamber 16, to be discharged to the bottom-ofthe well through the depending pipe 11. Since the diameter of the head12 is wider than that of the upper end of the body 3, there is thus nointerruption to said passage.

Having described my invention, what I Y claim `as new, and desire tosecure `by Letters Patent, is:

1. A sprayer-device, for air-lift pumps, comprising an orificed conduit,a chamber i-n communication therewith .and with a supply of air underpressure, and an inverted cone supported within said chamber, spacedfrom its inner walls and extending toward said .conduit coaXially-within the path of upward movement of air into the conduit, to deflectthe air toward the inner wall of the conduit. Y

2. A sprayer-device for air-lift pumps, comprising a conduit incommunication with a supply of liquid, and also at a lower level incommunication with a supply of flu-id under pressure, and a detlectorsupported in the conduit between its said communications, and adapted to.deflect the flu-id upwardly toward the wal-ls of the conduit .obliquelyand against the liquid in the conduit thereabove.

.sprayer-device dior air-lift pumps, comprising an upwardly directedconduit, a tubular Loriiced chamber below and in communication with t'helower end of said conduit, a tubular socket supported centrally in saidchamber spaced concentrically therefrom and having a communicationthrough the wall of the 'chamber with a source of air under pressure,and a spreader device mounted in said socket vbelow saidair-communication, having a contracted stem traversing the socketcentrally and an upwardly coned spreader-head .extending above thesocket and into the lower end of said oriced conduit, and adapted todeflect air entering from said source of supply upwardly and diverginglytoward the inner wall of the conduit below its orilices.

4. A sprayer-device for air-lift pumps, comprising a tubular chamber, a.tubular body supported therein in spacedrelation concentrically, alaterally-directed conduit communicating between the said tubular bodyand the outside of said chamber, and an upwardly coned sprayer-head withenlarged base seated in detachably and closing the hollow of saidtubular body below said lateral conduit, the latter delivering to thespace in said tubular body under said sprayer-head, and the top of saidsprayerhead being spaced concentrically from the inner wall of saidchamber and extending radially beyond the outer limit of the tubularbody.

5.-A sprayer-device for air-lift pumps, comprising an upwardly-directedconduit, a tubular chamber in communication with the lower end of theconduit, the lower end of the conduit being perforated immediately abovethe cham-ber, the lower end of the chamber being provided withengagingmeans adapted to disconnectibly engage the upper end of anotheralined conduit, said chamber having a cup containing a conicaldeliectin-g body mounted concentrically therein, and a conduit extendingfrom without into said chamber and said cup below the delecting-body,the said cup being supported within and spaced from the inner wall ofsaid chamber.

Signed a-t Waterloo, Iowa, this 12th day of April, 1915.
